IMPROVEMENT IN REVOLVING- CLTIVATOR.

The Schedule referred to in these Letters Patent and making part of thesame.

To ill .whom tt may concern.-

Be it known that I, ABRAHAM S. S'rnrnnns, of El Dorado, in the county ofFond du Lac, and State of Wisconsin, have invented a new and valuableImprove? ment in Revolving Cultivators; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the. same, reference being had to the annexed drawings,making a part of this speciiication, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a sectional View of my device;

I `igure` 2 is a plan view; and

Figure 3 is a detail.

My invention relates to that class of cultivators .in which the soil ismoved-and cultivated by means of teeth or plows, operated by a revolvingcylinder; and

It consists in providing a novelV combination of the various parts, theresult of which is a more perfect and efficient cultivator than hasheretofore been -devised of its class.

The letter A, ofthe drawings, represents the wheels of asulky-cultivator, constructed with a 'groove or grooves on the innersides of-.their hubs, respectively adapted to receive and actuate one ormore cords or bands upon each hub.

The letter Bis the axle-tree, and

Letters C are bars extending rearward from the axle, to the lower sideof which they are respectively pivoted, and united at their rear ends bythe cross-bar I). This cross-bar I) has a screw-thread cut on each ofits ends. A

Upon these threads, both inside and outside of the rs O I ad'ust nuts asshown on the drawings.

7. J r` i o These threads and nuts A'are used to "adjust the position ofthe rear endsof bars O'.

The letters c are adjustable standards, respectively attached to therear ends of bars O, in the manner rep-A resented. y I

The letters c are casters, attaohcdto the bottomsof standards a, asshown, and they are held inplace, and their distance from the bars C isregulated bythe bent rods s, constructed in the form, and operating inthe rf-MMV- manner represented on iig. 3.

The letter E is a revolving cylinder, adjusted to the lower side of bars0, in the manner shown, the letters c being wed ges tted in mort-ises insaid bars, and serving as bearings for said cylinder, on the upper sidethereof. Each endof cylinder E is provided with a drum, marked y,adapted to )receive and actuate suitable cords or bands,l by which thecylinder E is united with the carriage-wheels, and operated.

The letters uy are crooked shovels or teeth, adjusted in the cylinder E,in the manner shown. They are arranged in suitable numbers, and inregular order, and' each is bent in the manner represented.

IVhat I claim as my improvement, and desire to se cure by LettersPatent, is-

. The revolving cylinder E, adjustable standards a, casters c, bent rodss, teeth u, wedges fu, crossbar D, and drums y, combined and operatingwith the grooved wheel-hubs, and the bands or belts herein mentioned,substantially as speoied.

In testimony that'I claim the above, I have hereunto subscribed my name,in the presence of two witnesses.-
